Portraying Mad Max, Sadie Sink will, like her costar Finn Wolfhard, be joining a handful of horror projects. She'll play Haley in the horror movie Eli, which will be about a boy who goes to a secluded clinic that becomes a haunted prison of sorts. R.L. Stine readers should also rejoice because she'll be joining the Fear Street sequel in 2020.
